When implementing Hub Transport servers on Exchange 2010, you may have to configure multiple receive connectors. Because receive connectors are defined on the Hub Transport server itself, contrary to send connectors, you may end up defining each receive connector on each Hub Transport server. This gets painful when you need to implement the ForeFront Online Protection for Exchange servers in the Remote IP ranges for example.

Yes, you can create a script which configures the connectors for you, but wouldn’t it be nice if you can create definitions on one server using the GUI and then just copy and paste those definitions to the other Hub Transport servers? This script also allows you to simply duplicate existing Receive Connector definitions after adding an additional Hub Transport server afterwards, not only after the initial configuration of the Exchange environment.

In addition, you can specify whether you want to overwrite existing Receive Connector definitions (based on name) using the -Overwrite switch or clear all existing Receive Connectors before copying/importing using the -Clear switch.

So, let’s say you have two Hub Transport servers, L12EX1 and L12EX2. You have configured L12EX1 and you need to create the same set of receive connectors on L12EX2.

You can see in the example above, you can use the script to copy definitions from an existing server, e.g.

Copy-ReceiveConnector.ps1 –CopyFrom

You can also export and import settings, which may come in handy when you need to troubleshoot (you can have the customer export the receive connectors to a file) or when you want to prepare receive connector definitions off-site, e.g.

Copy-ReceiveConnector.ps1 –ExportTo .\conn.xml

Copy-ReceiveConnector.ps1 –ImportFrom .\conn.xml –Clear

Note that when ExchangeServer is specified as AuthMechanism on a receive connector, the FQDN needs to be set to the server’s FQDN, NetBIOS name or $null; in such cases I set it to the FQDN of the target server. Also, it uses the existing name, meaning you may need to rename the Default and Client connectors, which contain the server name, afterwards.

Update 24th August, 2012 (v1.1): Added find/replace in Receive Connector name so that “Default L12EX1″ on server L12EX1 will become or match with “Default L12EX2″ on server L12EX2.
